Figure 2: Influence of LFG and LEF-1 on proliferation and apoptosis. A. MCF-7 cells were transfected with siLEF-1 for 48h and the cell viability was determined using the cell viability assay. B. MCF-7 cells were transfected with siLFG, for 48h and analysed for activated levels of caspase 3 using the Caspase Assay. Data are the means ± SD of triplicate determinations which were repeated in three separate experiments. *p<0.05, ***p<0.001 vs. the control.
